Bible verses about "apostates" | ACV

¹¹ But now I write to you not to associate if any man who is called a brother is a fornicator, or a greedy man, or an idolater, or a slanderer, or a drunkard, or a predator, not even to eat with such kind.

¹⁰ If any man comes to you, and does not bring this doctrine, do not receive him into a house, and do not speak to him to rejoice. ¹¹ For he who speaks to him to rejoice, partakes of his evil works.
